Towards Trust-Aware Resource Management in Grid Computing Systems

IEEE CCECE2002. Canadian Conference on Electrical and Computer Engineering. Conference Proceedings (Cat. No.02CH37373), 2002

A Grid computing system is a geographically distributed environment with autonomous domains that share resources amongst themselves. One primary goal of such a Grid environment is to encourage domain-to-domain interactions and increase the confidence of domains to use or share resources (a) without losing control over their own resources, and (b) ensuring confidentiality for others. To achieve this, the "trust" notion needs to be addressed so that trustworthiness makes such geographically distributed systems become more attractive and reliable for day-today use. In this paper, we view trust in two steps: (a) verifying the identity of an entity and what that identity is authorized to do, and (b) monitoring and managing the behavior of the entity and building a trust level based on that behavior. The identity trust has been the focus of many researchers, but unfortunately the behavior trust did not catch much attention. We present a formal definition of behavior trust and reputation and discuss a behavior trust management architecture that models the process of evolving and managing of behavior trust in Grid computing Systems.

Grid computing is a paradigm for distributed computation on shared resources. It uses a large-scale, highly decentralized infrastructure, in which a huge number of participants share heterogeneous resources for a given purpose.

Security is a principal concern in offering an infrastructure for the formation of general-purpose computational grids. A number of grid implementations have been devised to deal with the security concerns by authenticating the users, hosts and their interactions in an appropriate fashion. Resource management systems that are sophisticated and secured are inevitable for the efficient and beneficial deployment of grid computing services. The chief factors that can be problematic in the secured selection of grid resources are the wide range of selection and the high degree of strangeness. Moreover, the lack of a higher degree of confidence relationship is likely to prevent efficient resource allocation and utilisation. In this paper, we present an efficient approach for the secured selection of grid resources, so as to achieve secure execution of the jobs. This approach utilises trust and reputation for securely selecting the grid resources. To start with, the self-protection capability and reputation weightage of all the entities are computed, and based on those values, the trust factor (TF) of all the entities are determined. The reputation weightage of an entity is the measure of both the user's feedback and other entities' feedback. Those entities with higher TF values are selected for the secured execution of jobs. To make the proposed approach more comprehensive, a novel method is employed for evaluating the user's feedback on the basis of the existing feedbacks available regarding the entities. This approach is proved to be scalable for an increased number of user jobs and grid entities. The experimentation portrays that this approach offers desirable efficiency in the secured selection of grid resources.

Trusted Grid computing demands robust resource allocation with security assurance at all resource sites. Large-scale Grid applications are being hindered by lack of security assurance from remote resource sites. We developed a security-binding scheme through site reputation assessment and trust integration across Grid sites. We do not treat the trust factor deterministically. Instead, we apply fuzzy theory to handle the fuzziness or uncertainties behind all trust attributes. The binding is achieved by periodic exchange of site security information and matchmaking to satisfy user job demands. PKI-based trust model supports Grids in multi-site authentication and single sign-on operations. However, cross certificates are inadequate to assess local security conditions at Grid sites. We propose a new fuzzy-logic trust model for distributed trust aggregation through fuzzification and integration of security attributes. We introduce the trust index of a Grid site, which is determined by site reputation from its track record and self-defense capability attributed to the risk conditions and hardware and software defenses deployed at a Grid site. A Secure Grid Outsourcing (SeGO) system is designed for secure scheduling a large number of autonomous and indivisible jobs to Grid sites. Significant performance gains are observed after trust aggregation, which is evaluated by running scalable NAS and PSA workloads over simulated Grids. Our security-binding scheme scales well with increasing user jobs and Grid sites. The new scheme can guide the security upgrade of Grid sites and predict the Grid performance of large workloads under risky conditions.

For a highly computational resource sharing grid environment, reliable transactions between entities is a major requirement. This is possible when not only do the users of the grid have an appropriate mechanism to select resource providers but the grid users must also pass through proper access control mechanisms placed by the resource providers Traditional Identity based access control methods are not applicable for grids because relationship between users and resource providers are ad hoc and dynamic, no central policy will be applicable. In this paper, users identify reputed resource providers by applying Fuzzy inference system on recommendation taken from its trustworthy acquaintances. The resource providers apply binary logistic regression on factors that influence the decision whether to allow a requesting user to use the grid or not.

Grid computing allows sharing of services and resources distributed over geographically dispersed, heterogeneous, autonomous administrative domains. As a domain generally has no idea about the trustworthiness of other domains, it may hesitate in accessing shared services and resources provided by other domains. Accessing resources and services from untrusted domains may pose dangerous consequences to the source domain. Trust is an important parameter in achieving faithful domain to domain interaction. Domains must be able to determine the trustworthiness of each other for the access of a particular service. Domains must also provide trust based access to resources and services that they expose in the environment. This paper describes different facets associated with trust issues among different entities in a grid environment and proposes a trust model to establish and manage trust relationships. The trust model provides support to calculate direct as well as recommended trust. Based on this model, a trust based authorization framework is proposed that can be used to provide trust based access to grid services. The goal of the model is to encourage trust based domain to domain interaction and increase the confidence of domains in accessing shared resources provided by other domains. The framework has been implemented in .NET environment with the support of WSE 3.0 toolkit. The framework has been evaluated by implementing a scenario that involves enforcement of different trust policies. The time taken by the enforcement component to evaluate trust policies has been noted. The results obtained from the implementation imply that the approach is workable and can be used to provide trust based access to grid services.

Grid computing is a wide area distributed parallel computing environment where it focuses on communication among different heterogeneous devices and harnesses unused processor cycles of all computers in a network for solving critical problems too intensive for any stand-alone machine. In this scenario security is vital concern because of dynamic allocation of users and resources. Among all other security issues trust establishment is given first priority.In this paper, we propose a novel model for resource selection in Grid computing environment. This model is truly unique model where decision is based on computed total trust which includes transaction, feedbacks, reputation, similarity, activity, popularity and obviously the total trust of the resources. The final decision is depend on the total trust of each resource. So the main motto of our project is to retrieve the best resource among the resources in grid environment. This paper provides a model which will allow only dependable transactions in grid by using total trust as a measure for the resources.

The Grid vision is to allow compute resources to be shared and utilised globally, with these distributed resources belonging to the same Virtual Organisation (VO). These resources execute jobs submitted by users, who are not in the resources' local domain and hence have no control over these resources. Conversely these users are not controlled by the resource owners. Certificates provide a common, useful security mechanism to overcome these barriers and set out access rights, but they do not guarantee that the resources, or users, can be trusted. This is due to the fact that resources and users may be unreliable; this situation may not be reflected in the users' perception of the reliability of the resource owner as a whole or vice versa. This paper describes a trust framework model for Grid computing, which enables users to execute their jobs on reliable and efficient resources, thereby satisfying clients' quality-of-service (QoS) requirements.
